Electrons are minute particles that exist within the molecular structure of a substance. When it comes in the form of lightning, this force can set fire to foliage and damage buildings.To prevent lightning damage to buildings in areas prone to lightning storms, building owners often install devices called lightning rods that attract the lightning charge to a high metal rod, which redirects and dispels the current underground. When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance. Electricity - Electricity - Alternating-current circuits: Certain circuits include sources of alternating electromotive forces of the sinusoidal form V = V0 cos(ωt) or V = V0 sin(ωt).
